| lstseq.greedy {delt} | R Documentation |
Calculates a scale of greedy histograms. The histograms in the scale have a partition of growing cardinality. Returns a sequence of estimates as piecewise constant functions and optionally as level set trees. Optionally a shape tree for a level set of each estimate is calculated.
lstseq.greedy(dendat, maxleaf, lstree = NULL, level = NULL)
dendat |
n*d data matrix |
maxleaf |
integer>1; the scale consists of histograms whose partitions have cardinality 1,...,maxleaf |
lstree |
if NULL, then level set trees are not calculated |
level |
if NULL, then shape trees are not calculated; if positive number, then it is the level of the level sets for which the shape trees are calculated |
A list with components
lstseq |
a list of level set trees |
pcfseq |
a list of piecewise constant functions |
stseq |
a list of shape trees |
hseq |
a vector of smoothing parameters corresponding to the members in the sequences; the smoothing parameter is the cardinality of the partition |
